Application January 13, 1937; `serial No. 120,443 1 claim. (ci. V10i- 340) This-invention appertains to new and useful improvements in ink fountains for platen printing presses.

The principal object of the present invention is to provide an ink fountain of the character stated devised to save time, ink and afford a perfect distribution of ink on all size jobs of printing.

Another important object of the invention is to provide :an ink fountain for platen printing presses wherein a removable ink containing can is provided and removably supported so that it can be replaced from time to time as different colored ink is desired.

Still another important object of the invention is to provide an ink fountain for platen printing presses wherein a lift mechanism is employed for lifting the inking roller and ink can clear' of the usual form roller at proper intervals of operation.

These and various other important objects and advantages of operation will become apparent to the reader of the following specification.

In the drawings:-

Figure 1 represents a top plan view of the inking apparatus, the press being shown in broken lines.

Figure 2 is a side elevational view of the inking mechanism.

Figure 3 is an enlarged vertical sectional View taken substantially on the line 3-3 of Figure 1. 30 Figure 4 is a transverse vertical sectional view of the ink can and roller.

Figure 5 is a vertical sectional View taken substantially on the line 5 5 of Figure 3.

Figure 6 is a fragmentary sectional view of the ink can.

Referring to the drawings wherein like numerals designate like parts, it can be seen in Figure 2 that numeral 5 generally refers to the platen type printing press which is provided with the usual side arm 6. Numeral 1 is the attachment side arm which has a swiveled boss; 8 at its lower end through which the connecting rod 9 is disposed. This rod 9 is adjustably disposed through the upper portion of the clamp Il] on the arm 6 and to afford adjustment, the rod 9 is threaded at one end as at Il and has the nut I2 thereon.

Mounted upon the press 5 are the uprights I3-I3 secured to the press by screws I4. Journaled through these uprights I3 are the end portions of the shaft I5, the shaft I5 having a laterally disposed member I6 secured by the collar I1 thereto and to this member I6 is secured the arm 1 at its upper end as denoted by numeral I8.

On the shaft I5 are the collars I9 from which extend the channeled members 20 through which the bars 2I-2I extend. YThe upper ends of the uprights i3 are equipped with laterally disposed lugs 22 through which the set screws 23 are vertically disposed to serve as adjusting means for the channeled carrier 2B, the bars 2| being secured to the carriers 20 by machine screws 24.

As is shown in Figure 2, each of the bars 2l is provided at its forward end with a pair of triangular-shaped blocks 25 thereon over which are disposed the corresponding end portions of the angle iron members 2li-26, these angle iron members being secured to the blocks 25 by screws 21.

Numeral 28 represents the ink can having the removable slip type cover 29. The lower portion of the can has converging side wall portions 30 for rest on the opposed inclined sides of the angle iron members 26.

The side walls of the can 28 are provided with depending apron portions 3l in which the rectangular-shaped frame structure 32 snugly fits. Bracket members generally referred to by numeral 33 and consisting of vertically extending straps 34 bent laterally at their upper ends as at 35 and in the same direction as at 36 at their lower end portions and then upwardly as at 31 and outwardly as at 38 are provided and used in the manner shown in Figure 3. The lateral portions 38 are secured by screws 39 to the ends of the aforementioned frame 32 while the end Walls of the can 28 rest upon the portion 36 thereof. A cross bar 40 disposed over the top 29 of the can has openings in the end thereof through which depend the stems 4I of the knobs 42 and these stems are provided with threads at their lower ends for disposition through the threaded openings in the lugs 35 of the brackets 33. Coiled compressible springs 43 are provided on the stems 4I and interposed between the ends of the bar 40 and the lugs 35. The end portions of the frame 32 are cut away to receive the bearing block 44 (see Figure 5)` into which the pintles 45 at the end of the rol1er'46 extend. Machine screws 41 are employed for securing the bearing blocks 44 to the frame 32 as in the manner shown in Figure 5. Suitable guides or bailles 48 are provided in the frame 32 for directing the ink to the roller 46.

In addition to the cross bar 40, a transversely extending bar 49 is provided on the bar 40 and this is provided with barrel-like formations 50 at its ends through which the upper ends of the rod 5I extend. These rods 5I are provided with hooks 52 at their lower ends for engagement under the angle members 26 while the upper ends are threaded and provided with wing nuts 53 thereon which are threaded downwardly to exert pressure against the barrels 50. Coiled compressib-le springs 54 are provided on the rods 5|. Y c

Obviously when it is desired to change the color of the ink, all that is required is that the bars dll-49 be removed so that the can 28 can be displaced and another can containing the desired color substituted.

In the operation of the device, the attachment arm I is operated by the arm B causing a rocking motion of the bars 2l. is designed to lift the roller 46 and can 28 clear of the form roller just at the proper time.V

When the form roller (not shown) on its upward travel passes under the roller 46 and has received v a fresh supply of ink, the roller is lifted clear of the form roller by means of this lift mechanism. While the foregoing specication sets forth the invention in specic terms, it is to be understood that numerous changes in the shape, size and materials may be resorted to without departing from the spirit and scope ofv the invention as claimed hereinafter.

Having described the claimed as new is invention what is This lift mechanism In combination with a platen printing press, a

rockable structure, connecting means between the rockable structure and a movable part of the press, a removable ink receptacle supported by the rockable structure for supplying ink to the usual form roller of the press, said ink receptacle consisting of a rectangular frame-like structure, a pair of channeled members disposed transversely on the rockable structure and adapted for supporting the receptacle, said frame-like structure being supported by the lower portion ot the receptacle and defining the outlet for the receptacle, a roller mounted in the said frame-like structure, a closure for the top of the receptacle, a bridge piece disposed across the closure and having openings in the ends thereof, vertically disposed hook members extending through the openings in the bridge member, said hook members having their lower ends hookedly engaged with the said channeled members, and securing means at the upper ends of the hook members bearing against the end portions of the said bridge member.
